4.2/ 5

VerdictThe Hiearcool 7-in-1 nails the basics of a travel dongle — small, plug-and-play, and cheap — but its 30Hz HDMI cap means it's a companion for productivity, not a display upgrade for gaming or video work.

Hiearcool 7-in-1 USB-C Hub

Editorial review

Intro

At $25.99, the Hiearcool 7-in-1 USB-C Hub isn't trying to be your all-day docking station — it's trying to be the thing you toss in a laptop bag and forget about until you need an extra port. For the most part, it succeeds at that narrow job, but a couple of spec-sheet compromises mean it's worth knowing exactly what you're buying before you check out.

What's in the box, and why it matters

The port lineup is straightforward: one HDMI output, two USB-A 3.0 ports rated at 5Gbps, an SD and microSD card reader, and a USB-C PD input for pass-through power. That's seven functions crammed into a dongle small enough to disappear in a pocket — which is the whole appeal here. If you're a MacBook or ultrabook user who lost all your ports to a thin chassis, this hub restores the basics without adding bulk to your bag.

The fixed USB-C cable (rather than a swappable or captive-connector design) keeps things simple, and combined with genuinely wide device compatibility, this is a hub you can hand to almost anyone with a USB-C laptop and expect it to just work. There's no driver installation, no companion software, no fiddling — plug it in and your display, card reader, and USB peripherals show up. For non-technical users or anyone who just wants a dongle that behaves like a dumb, reliable accessory, that plug-and-play simplicity is worth more than a longer spec sheet.

The HDMI caveat you need to know about

Here's the catch: the HDMI output supports 4K, but only at 30Hz, not 60Hz. In practice, 30Hz is noticeably choppier for anything with motion — cursor movement feels laggy, scrolling looks stuttery, and video playback loses smoothness compared to a 60Hz connection. If you're plugging into a 4K monitor purely to view static content — spreadsheets, documents, code, email — you likely won't notice or care. But if you were hoping to use this hub to drive a 4K display for video editing, gaming, or just a smoother everyday desktop experience, this is the spec that will disappoint you. It's the single biggest thing to understand about this hub before buying: it checks the
